BRACELET.

Patented June 19, 1906.

Application'filed January 6, 1906. Serial No. 294:;934.

To (ZZZ whom may concern:

Be it known that I, TH oDo-R-n W. Fos'rnn,

:a citizen of the United States, residing at Providence, in thecounty'of Providenceand State ofRhode Island, have invented a new anduseful Improvement in Bracelets, of which the following is aspecification.

This invention has r 'ferenceto an improvement in bracelets, and moreparticularly to an improvement in concealed hinges for bracelets.

The object of my invention is to improve the construction of a concealedhinge for bracelets whereby the interlocking hinge pivotally securedtogether under spring tension Without the use of the nsual pintle, andthe hinge has a limited opening movement.

My invention consists in the peculiar and novel construction of aconcealed hinge-for bracelets, with details of construction, as will bemore fully set forth hereinafter.

Figure 1 is a side view of a two-part bracelet provided with my improvedconcealed hinge and showing the bracelet in the closed position in fulllines and in the 0 en position in broken lines. Fig. 2 is an enl argeddetail sectional view of the hinge end of the bracelet looking at theoutside face of the hinge. Fig. 3 is an enlarged detail sectional viewtaken on line 3 3 of Fig. 2 through the hinge and adjacent ends of thebracelet and show- Fig. 4. is an enlarged detail sectional view similarto Fig. 3 and showing the hinge in the open osition. Fig. 5 is anenlarged detail V16W.l )0l ing at the outside face of one of theinterlock ing hinge members; and Fig. 6 is a sectional view through oneof the hinge members ,taken on line 6 6 of Fig. 5.

In the drawings,'c indicates one semi-oval half, d the other semi-ovalhalf, and e the concealed hinge of the bracelet. Thesemi-oval halves cand d are constructed from a tube which is oval in" cross-section. The uper half a has the end 0 for the hinge e'and the The lower half d hasthe end (1 for the hinge e andthe end (1 The ends 0 and d and the ends 0and d coincide when the bracelet is closed. The ends a and (1 may beprovided with any one of the well-known forms of catches adapted to holdthe ends to gether when the bracelet is closed.

My improved concealed hinge e consists of two identical interlockingmembers e e.

These-members e e are shaped to fit in the ends-c" and (Z of thebracelet and curved to conform to the contour of the bracelet, as shownin Figs. 3 and 6. Each member 6 is constructed integral to have a solidend 6 from which extends a rigid arm 6 cut away at e to form acentralarm e having on its inner face a groove 6 adjacent its end =at=its end.The inner end of the'lip 6 forms a stop-shoulder-e and-in formingthegroovee and the lip e a raised portion 6 and a depressed portion a areformed in the inner face of the arm a as shown in Figs. 5 and 6. Aspring side arm 6 extends from thesolid end 6 parallel with the arm cand forms a space 0 as shown in Fig. 5. The center on which the groove eand the lip e is struck coincides with the center on which the hingeopens. a

The two membersof the hinge are assembled by forcing the central arms ee of each ,member into the spaces e 6 (against the tension of thespring-arms e e) and'bringing the arms into a position for the lip e eto enter the coinciding grooves e c with the hinge members on acurvedline with each other, as shown in Figs. 2 and 3. The members of thehinge are now forced into the ends 0 and d of the bracelet into aposition for the center on which the hinge opens to coincide with thejuncture of the ends 0 and d of the bracelet. The solidends e c of thehinge members are now secured in the ends 0 and. d of the bracelet bysolder or other means.

The hinge is limited in its opening movement by the-stop-shoulders e con the inner ends of the lips e e engaging with each other, as shown inbroken lines in Fig. 4. The tension of the spring-arms e e on the arms 66 tends to firmly hold the lips e e in the grooves e e and compensatesfor wear on the coinciding faces of the arms 6 e Also the comparativelylarge faces of the raised portions e e, engaging with the faces of thedepressed portions 6 8 practically eliminates wear on the faces of thelips e 6 thereby providing a bracelet with a concealed hinge that is notliable to wear the ends 0 and d alinement.

Having thus described my invention, I claim as new and Patent 1. In abracelet, a concealed hinge comprising two identical interlockin memberseach member having a solid end om which extends a rigid arm cutaway toform an arm of the braceletout of and'the lip e loose and throw desireto secure by Letters IIO having on its inner face a groove, a lip, araised and a depressed portion intermediate the groove and the lip, anda spring side arm parallel with the central arm and forming anintermediate s ace, as described.

2. A concea ed bracelet-hinge comprising two identical interlockingmembers 6 a each. member a 6 having a solid. end 6 from which extends arigid arm 6 cut away at a" to form an arm 0 having on its inner face agroove 0", a lip 0 the inner end of which forms a stopshoulder a araised portion e and a depressed portion 6 intermediate the groove 6 andthe lip e and a spring side arm 6 extending from the end. 6 parallelwith the arm a as described.

3. The combination with a tubular half 0 having the end 0 and a tubularhalf (1 having the end (1 of a bracelet, of a concealed hinge e composedof two identical interlocking members a a each member a 0 having a solidend a from which extends a rigid arm a cut away at e to form an arm ahaving on its inner face a groove e a lip e the inner end of which formsa stop-shoulder a a raised portion a and a depressed portion 0intermediate the groove 0 and the lip 07, and a spring sidearm eextending from the end a parallel with the arm a as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

THEODORE FOSTER.
